For thousands of years, humans have worshiped the gods of the heavenly world, but faith has been on the decline since a celestial last graced the earth. That is, until a scorned princess with a target on her back is miraculously rescued by one. Hunted down by soldiers from her own nation, Princess Chaeyeon is in a desperate battle for her life. As if to answer her prayers, a mysterious man with wings swoops down from the sky, whisking Chaeyeon away to the land of Mount Kunlun, home of the Great Celestial Phoenix who will soon become her husband. Blessed with this unprecedented opportunity, Chaeyeon is determined to become the Celestial Bride and right the wrongs of her past. In doing so, she may just change the course of her fate, both on Earth and in Heaven.
